Title: Suspension system using variable shock absorbers - has selection of damping value limited to defined range dependent on detected travel characteristics
Inventor: BUTSUEN TETSURO
IPC: F16F9/46
Filed: 1991-10-28
Abstract: The suspension system uses shock absorbers (1), each of which has a damping valve which can be adjusted between at least three different damping valves, dependent on the travel characteristics of the vehicle. The travel characteristics are used to limit the possible number of damping values from which the current damping value can be selected, using a given control rule. The control rule has a threshold value for limiting the damping value to an upper or lower range, in dependence on the oscillation characteristic, e.g. the detected absolute velocity of the suspension spring.

Patent DE-4209549-A1 (DE)
IPC: C10J3/66
Filed: 1992-03-24
Abstract: A process was to be developed, by means of which the residual materials arising in the separate collection and sorting of packaging materials and the like can be utilized for producing a synthesis gas and at the same time the pollution potential inherent in the residual materials is destroyed and the formation of new pollutants is prevented. This is effected in such a way that, after a pyrolysis reaction at temperatures from 300-500 DEG C, the metallic constituents are separated off and the remaining solid phase is charged to a gasification stage and gasified at temperatures between 1450 and 1850 DEG C with oxygen-enriched air or oxygen under reducing conditions. The ash fractions arising in the gasification stage are taken off in the form of a vitrified slag, and the gas phase leaving the pyrolysis is converted to synthesis gas together with the gases formed in the gasification stage at temperatures between 800 and 1250 DEG C, with simultaneous addition of steam. Apparatus for carrying out the process consists of a rotary pipe reactor which has a gas outflow line for the pyrolysis gases formed at the end opposite the charging side. On the solids take-off side, the rotary pipe is connected to a metal separator device and a gasification reactor which is connected via a gas outlet to a decomposition reactor, the pyrolysis gases taken off from the rotary pipe reactor and steam also being introduced into the decomposition reactor. The crude synthesis gas formed is discharged from the decomposition reactor via a cooling and scrubbing device.

Title: Potentiometer for converting physical parameter to electrical form - has current fed into slider, ends connected to current-voltage converter and inverter forming normalised output
Inventor: EBERHARDT PETER DR
IPC: G01D5/165
Filed: 1992-05-19
Abstract: The potentiometer (10) has a resistive track on which a slider (11) moved by a physical parameter slides. A current (Is) fed to the slider is divided according to the variable potentiometer resistance (R1,R2) and slider position and the resulting variable partial current or currents evaluated. At least one of the partial currents is fed from the ends (10a,10b) of the potentiometer to a current-voltage converter. For evaluation of each partial current an inversion is performed after conversion to produce a normalised, positive output voltage over the displacement range of the potentiometer. ADVANTAGE - Any transfer resistance can between potentiometer slider and resistance track can be made to appear as null without direct additional circuitry. Highly accurate measurement and evaluation are achieved using simple state-of-the-art electronic circuitry.

Inventor: HENDEL HORST DIPL ING
IPC: H01H51/00
Filed: 1992-06-17
Abstract: In a relay, a holding pin for a contact spring is arranged in the area between the armature and the coil in such a way that the load current that flows in the contact spring can flow through the ferromagnetic circuit consisting of the core, the yoke (12) and the armature (13).

The connection pin (110) conducts the load current of the contact spring through a hoop section (111) that extends over the armature. Alternatively, the holding pin (9) of the contact spring may also be additionally contacted with part of the load current, in order to make use of certain effects of the current loop.
